Dr. Sands is well known for his outstanding five volume "Catfishes of the World" series and his studies
of Corydoras. My question about this book is, what happened? This "new" book is basically a reprint of Sands' "A
Fishkeeper's Guide to African and Asian Catfishes" (1986:Tetra) and his "A Fishkeeper's Guide to South American
Catfishes" (1988: Tetra). This book contains the same old information, and many of the same old pictures, already
published in the two Tetra / Salamander books.

The book opens with a chapter entitled "Aquarium" which covers the nocturnal aquarium, aquascaping and
water. There really is nothing in this section that is not included in every basic aquarium book. The only notable item
in this section are the beautiful photos of South American landscapes. The entire book, as we might expect, has a
strong leaning to the catfishes of South America.

The second, third, and fourth chapters cover South American, African and Asian, and cold water catfishes
respectively. The South American section covers specific information on well over one hundred different species. These
are all the same species as Sands covered in his Tetra book on South American catfishes. The information is so similar
that it would certainly qualify as plagiarism if Sands himself had not written both books. Sands did update the South
American section with the proper scientific names, however, the rest of the book was never updated.

The section on African and Asian catfishes covers a pitiful fourteen Asian catfishes and forty African
catfishes (most of which are Synodontis). The complete lack of research in this section is glaring. Of the fourteen
Asian species, Sands places them all in the family Bagridae despite that fact that there are six families represented.
Sands also places numerous African families in Bagridae despite the fact that these fish were all assigned to new
families nearly a decade before the Back to Nature Guide went to press. These problems make the book useless as an
identification guide. Many, perhaps most, of the photographs in this section misidentify the pictured fish. For
example, on page 101 the pictures are labeled:

Mystus micracanthus (the pictured fish is Mystus bimaculatus)

Mystus nemerus (the pictured fish is Hemibagrus wyckioides)

Mystus species of the "vittatus" group (One fish IS Mystus vittatus from India and
the other is the only distantly related Mystus mysticetus from Thailand)

Mystus tengara (the pictured fish is Mystus mysticetus)

The final section, with the curious title "Coldwater Catfishes" was obviously a last minute add on. The
chapter is two pages long and does not cover any specific species. The other strange thing is that of all the catfishes
that could have been included in this section, only the North American Ictalurids and the Asian Wels are discussed. The
many temperate species of Russia, China, North India, and Japan are completely excluded from the chapter. Even this
section did not escape the misidentification bug and a photograph of the yellow bullhead ( Ameiurus natalis) is
labelled Pylodictis olivaris.

If you have Sands' two Tetra books there is no reason to buy this one and as such is not what I would
call good value for the money.
